It would hurt, you'd probably get a blister, but you are unlikely to get rid of the wart.
observation is easy to explain... I you see some one put their hand in a fire and they get burnt. then you have learnt by looking what will happen to you if you do the same
Whilst cooking the Sunday lunch I burnt my hand on the hot roasting tray.
Because it's damaged by the heat.
You would get a photo of your hand. Other than that, not much if you only did it once or twice. It would be kind of like keeping a laptop on your lap.

Just listen to what they are asking. If they ask you for a light, light it for them. If they ask you for a lighter or a match hand them your lighter.

Heat travels up
The hot smelter burnt his hand to the bone.
When a hand is placed over a lit match, the air around the match gets heated and rises due to lower density. This creates a convection current where hot air rises and cooler air moves in to take its place. The movement of the hot air transfers heat to the hand, making it feel hot.
